CLEANING AND POLISHING COMPOSITION.

No Drawing.

A To all wkomzt ma concern:

Be it known t at I, CLARENCE P. Roam- SON, of Swarthm re, in the county of Delais capable o ware and in'the tate ofPennsylvania, have invented acertai'n new and useful Improvement in Cleaning and Polishing Compositions, and do hereby declare that the following is a full, clear, and exact descript1on thereof.

My invention relates particularly-to compositions adapted to be used for cleaning and polishing of various materials. I

The object of my invention is to provide a composition for removing grease, dirt and foreign matter of all kinds from the skin, as well as from metals and manyother kinds of materials. The object of my invention is particularlyto provide a composition of this character which contains a finely di-' vided prepared wood product, as well as a soap. The 'wood containedin the composition serves to enter the interstices of the surface bein cleaned, so as to forcibly remove accunnfiations from the same, but without injury to the surface being treated.

The object of my invention is, furthercharacter in the form of a powder which has the advantageous characteristics of being able to remove the insoluble dirt from the interstices of the skin or other surfaces, without injury to or scratchin the same, which f taking up 51c insoluble -dirt when loosened from the surface, and which is capable of emulsifying and absorbing the oily materials found on the surface to be cleaned.

More particularly the object of my invention is to provide a composition of this character in which the disadvantageous;charac teristics of previous compositions which result from the presence of objectionable oils,

resins, etc., and lack of absorbent qualities, as well as either deficient abradant'propere5 ties or tendency to produce scratching, are

avoided. i 7 Further ob ects of my inventlon will aptained hereinafter.

While my invention is capable of embodi- I I Specification of Letters Patent. Patented June 1?, I919 Application filed July 3, 1918 Serial No. 243,113.

ment in many difi'erent forms, for the purpose of illustration I shall describe only certain forms of my invention hereinafter.

For example, a composltion made in accordance with my invention may be comprised of Alkali free soap powder 20 to 40 parts.

Prepared wood to 80 parts. p

. The production of the prepared wood used in connection with my invention is an important feature thereof. To produce the prepared wood, I ut1l1ze saw-dust from fir or spruce, which saw-dust has become seasonedby standing in the air for a considerable period, which may be several..,years. This sawdust is ground to a fine powder between steel cylinders, such as are used in flour mills. The ground 1 saw-dust is then screened, and thereafter boiled in water for a} or more hours, in order to remove a considerable proportion of the objectionablev or longer, in order to acquire the desired abradant and absorbing qualities. The soap used in the above composition may be any suitable soap powder, and may, for example, be made of a soda soap.

-While I have described my invention above in detail, I wish it to be understood that many changes may be made therein, without departing from the spirit of my invention.

I claimt 1. A cleaning and polishing composition comprising a soap powder and a finely divided prepared wood having had oils and resins removed therefrom.

2. A- cleaning and polishing composition comprising a soap powder and-a finely divided prepared boiled Wood having had oils and resins removed therefrom.

3. A cleaning and polishing composition comprisinga soap powder'and a finely divided prepared, boiled and dried Wood having had oils and resins removed therefrom.
